Vitamin A

An underlooked vitamin

Since my girl Bartok had her wry neck episode, vitamin deficiencies in poultry have fascinated me.
I believe that if you can understand how a vitamin works, you can gain a deeper understanding of deficiencies.
After seeing a user on Instagram talk about how important Vitamin A is for chickens, I got curious!

Vitamin A is truly at the top of the vitamin chain. It is a fat-soluble vitamin, most often stored in the liver.

This vitamin ensures that epithelial cells are in good condition. These cells are found in the skin as well as the linings of the digestive, reproductive, and respiratory tracts.

In other words, this top-of-the-chain vitamin—Vitamin A—helps keep the following healthy:

  • Mucous membranes

  • Skin

  • Vision

  • Immune system stays healthy

Symptoms of Vitamin A deficiency in Poultry

Symptoms of Vitamin A deficiency in adult birds:

  • Ruffled feathers

  • Emaciation and weakness

  • Reduced egg production

  • Decreased hatch rate

  • Small ovarian follicles, some showing hemorrhage

  • Milky, cheesy discharge from the eyes and nostrils

  • Xerophthalmia, also known as dry eye

If a mother hen suffers from a Vitamin A deficiency, her chicks can inherit this deficiency. Depending on the amount of Vitamin A stored in the hen's liver, symptoms may appear within 7 days.

Some signs of Vitamin A deficiency in chicks:

  • Anorexia

  • Growth retardation

  • Loss of yellow pigment in shanks and beaks

  • Pale comb and wattles

  • Chicks usually die before discharge from the eyes and nostrils appears

Vitamin A rich foods
  • Green Kale
  • Pumpkin
  • Broccoli
  • Cantaloupe


My own speculations:
Reading about the side effects of Vitamim A deficincy, I do wonder how often its misstaken for a respiratory problem. 
The vitamin works in so many linings of diffrent tracts in the bird. So you could speculate what other side effects these birds get if the linings aint in healthy condition. 

 

Thats why my belief will always be that if you have a sick bird in any condition its good to supplement their treatment with a multivitamin.
